Objectives:

• define the concept of a system,

  
  

• recognize the Earth as a system composed of subsystems,

  
  

•   identify the visible features of the different Earth systems, and

• describe how the matter and energy flow across the Earth systems. 

Activity 1.1: Earth Systems Picture Analysis 

 Optional Materials Needed: • World Map, Google Earth (if internet connection is available) 

 Procedures: 1. List down at least three features on each system, an example per system is given as your guide: System Key Word System Features atmosphere air (Ex: clouds) biosphere life (Ex: trees) geosphere land (Ex: mountain) hydrosphere water (Ex: ocean)
